Sidney J. Brandt, New York, N. Y. Application April: 6.; 1942, Serial N 0. 437,755 3 Claims. (01. 131-232)' This invention relates to a mechanical means for cleaning a smoking pipe bowl'by pressing the pipe bowl upon the cleaner herein described;

This pressure causes a cleaning tool to enter the bowl and force the ashes and residue from the bowl into a receptacle.

Figure 1 is a central vertical view of the invention.

Figure 2 is a central vertical view of an embodiment of the invention.

Figure 2A is a fragmentary section of Figure 2 illustrating the slots cut through the turned in section of the sliding cover and the lips formed in the receptacle to coincide with these slots.

Figure 3 is a sectional view of the invention taken substantially on line 3-3 of Figures 1 and 2.

Figure 1 illustrates the cleaner adapted to an open receptacle. The cleaning tool I, that enters the pipe bowl is attached to a spiral rod 2. On the other end of the spiral rod is fastened a smooth fiat disk 3. A driving nut 4 travels on the spiral rod and is held at the extreme end of this rod by a spring 5 which is inserted between the disk and the driving nut. The driving nut is fastened to a tube 6 which slides in sleeve 7. This sleeve has a vertical groove into which a small lip of the tube enters. This lip slides in said groove and serves the dual purpose of keeping the tube and sleeve from being forced apart and preventing the tube from rotating. The disk rests on a convex surface formed by cap 8. A pipe rest 9 is fastened rigidly to the driving nut by means of bracket arms. The entire cleaner is attached to an open receptacle H).

In operation, the pressure of a pipe bowl upon pipe rest 9 forces the driving nut 4 downward, and causes spiral rod 2 to revolve. The cleaning tool I attached to the spiral rod turns with it. As the cleaning tool turns, it enters the pipe bowl removing the ashes and residue until it reaches the base of the bowl. The operator then releases the pressure on the pipe bowl and the cleaning tool recedes back to its original position. The ashes and residue fall from the pipe rest into the receptacle Ill.

In the embodiment shown in Figure 2, the pipe rest 9 of Figure 1 is replaced by the upper half of the container I2 of Figure 2 which also serves as a sliding cover over the lower half of the container Ill. The lower half of the container serves as a receptacle for ashes and residue. The cleaning tool I that enters the pipe bowl is attached to a spiral rod 2. On the other end of the spiral rod is fastened a smooth flat disk 3. A driving nut 4 travels on the spiral rod and is held at the extreme end of this rod by a spring 5 which is inserted between the disk and the driving nut. The driving nut is fastened to a tube '6 which slides in sleeve 1. This sleeve has a vertical groove into which a small lip of the tube enters. This lip slides in said groove and serves the dual purpose of keeping the tube and sleeve from being forced apart, and preventing the tube from rotating. The disk rests on a convex surface formed by cap 8. Bracket arms ll fix the sliding cover rigidly to the driving nut 4. The cap 8 is not attached to, but only rests on the bottom of the receptacle. The edge of the sliding cover that overlaps the receptacle is turned in and several slots are cut through this turned in section, see Figure 2A. An equal number of lips are formed in the edge of the receptacle to coincide with these slots. Thelips are used to prevent the sliding cover and the receptacle from coming apart.

To reassemble the receptacle with the sliding cover after cleaning the receptacle; the bottom of the receptacle is pushed against the cap 8, so as to compress spring 5 slightly; the lips are pushed through the slots cut in the turned in edge of the sliding cover. A slight twist is given the receptacle before it is released. The lips then rest on the turned in edge of the sliding cover.

When the operator presses a pipe bowl on the sliding cover l2, it is forced downward and slides over the receptacle as the cleaning tool I enters the pipe bowl with a twisting motion and cleans it. When the pressure is removed from the sliding cover. it returns to its original position until stopped by the lips of the receptacle.

I claim:

1. A mechanical pipe bowl cleaner operated by pressing a pipe bowl upon the cleaner which pressure causes a cleaning tool to rotate and enter the pipe bowl, and comprising a spiral rod with a cleaning tool attached to one end and a fiat disk attached to the other end; a pipe rest attached to a driving nut which travels on the spiral rod and causes the latter to rotate by engaging its spiral; a spring inserted between the ilat disk and the driving nut, said spring tending to keep the two apart; a tube fastened to the driving nut, said tube sliding in a sleeve which has a vertical groove into which a small lip of the tube enters and acts as a guide and stop, and keeps the tube from rotating; and a cap provided with a convex surface and fastened to one end of the sleeve and upon which the fiat disk rests and rotates.

2. A mechanical pipe bowl cleaner operated by pressing a pipe bowl upon the cleaner which pressure causes a cleaning tool to rotate and enter the pipe bowl, and comprising a spiral rod with a cleaning tool attached to one end and a flat disk attached to the other end; a pipe rest attached to a driving nut which travels on the spiral rod and causes the latter to rotate by engaging its spiral; a spring inserted between the flat disk and the driving nut, said spring tending to keep the two apart; a tube fastened to the driving nut, said tube sliding in a sleeve which has a vertical groove into which a small lip of the tube enters and acts as a guide and stop, and keeps the tube from rotating; a cap.

provided with a convex surface and fastened to one end of the sleeve and upon which the flat disk rests and rotates; and an ash collecting receptacle to which the sleeve is fastened.

3. A mechanical pipe bowl cleaner operated by pressing a pipe bowl upon the cleaner which pressure causes a cleaning tool to rotate and enter the pipe bowl, and comprising a spiral rod with a cleaning tool attached to one end and a flat disk attached to the other end; a driving nut which travels on the spiral rod and causes the latter to rotate by engaging its spiral; a spring inserted between the flat disk and the driving nut, said spring tending to keep the two apart; a tube fastened to the driving nut, said tube sliding in a sleeve which has a vertical groove into which a small lip of the tube enters and acts as a guide and stop, and keeps the tube from rotating; a cap provided with a convex surface and fastened to one end of the sleeve and upon which the flat disk rests and rotates; a container for collecting ashes and to keep the mechanical parts from view; said container being split into two halves, an upper and a lower, the upper sliding over the lower and only the upper attached to the driving nut by means of bracket arms; a number of lips formed in the lower half of the container to coincide with slots in a turned-in rim in the upper half of the container, said lips engaging said rim when the upper half of the container is given a twist, to keep the container together.
